Does anyone else has a problem starting Chaos Cosmos (OSX)

[frv]

Hi,
I can't get Cosmos to work on my Macbook m1. Tried everything. Version 12 hot fix and 13.
OSX 15.0
C4D 24.5.1 and 25.0.1

Downloaded the latest Cosmos without any luck.
Followed the instructions but nothing.
Tried to send a support ticket but the menu pull downs on the website guided me to a request ticket that left me no option for support on this issue. I am tired of Chaos Cosmos by now so it could be me too.

I am getting scared to update my main system the Mac Studio and crashing it on Cosmos for CR12 and 13. I use Cosmos a lot in current projects and can't afford to be left without so I will stick with C4D 2024 for now.

Any help appreciated. When I start Cosmos I get the window I uploaded as an attachment.

I got CR 12 hot fix working on my Mac Studio with C4D 2024 and OSX 14.6.1.

Can the Coronarender team confirm not to update to OSX 15 and or C4D 2025 because of Cosmos incompatibility. I know from my laptop that the above does not work with OSX 15. CR13 do C4D2025 neither.

Hello @frv,
Thank you for bringing this to our attention.
This will be further investigated.
In the meantime, I'd say try to wait a little bit more before upgrading your OS while we investigate this.
On the other hand, have you already tried following the instructions from the pop-up window? (from your screenshot)
Sorry for the inconvenience.
We'll keep you posted.
Cheers!

Hi Benjamin,
thanks for the update.
On my laptop m1 OSX I did not get Cosmos to work anymore after updating to OSX15.
But its difficult to tell what the cause is since I also updated C4D to 2025 and was using the daily build 13 (September one).
I then downloaded 12 again and I could not get Cosmos to work anymore.

On my Mac Studio OSX 14.6.1 with CR12 hot fix (was using the daily builds 13) and C4D2024 I got Cosmos normally working again after a few glitches where Cosmos did not want to start up directly.
I don't exactly know how to go from C4D2025 back to 2024 on my laptop m1 to see if I its just the OSX15 or C4D2025 which one is to blame.

Am in the middle of a project so can't do much in terms of testing and without Cosmos I no longer have a project... so I don't want to risk my Mac Studio messing up the current working installation.

I tried the instructions that Cosmos popup window provided on my laptop but without luck.
